Devices using membrane mediated forward osmosis

摘要

A forward osmosis device, method of manufacturing the forward osmosis device and method of using a solution produced using the forward osmosis device utilizes a forward osmosis membrane element positioned within a housing of the device between an input chamber and an output chamber to draw liquid from the input chamber to the output chamber via an osmotic process. The forward osmosis membrane element includes a layer of purifying additives on the forward osmosis membrane element to remove contaminants in the liquid as the liquid is drawn through the forward osmosis membrane element. In an embodiment, the forward osmosis device is a forward osmosis intravenous (IV) bag.

主权项

1. A forward osmosis device comprising:
a housing having an input chamber and an output chamber, the housing including an inlet connected to the input chamber and an outlet connected to the output chamber; draw solutes in the output chamber of the housing; and a forward osmosis membrane element positioned within the housing between the input chamber and the output chamber, the forward osmosis membrane element being configured to draw liquid placed in the input chamber through the inlet into the output chamber containing the draw solutes via an osmotic process, the forward osmosis membrane element including a layer of purifying additives on the forward osmosis membrane element to remove contaminants in the liquid as the liquid is drawn through the forward osmosis membrane element, wherein the layer of purifying additives includes Hydromethane Sulfinate.
